Be it known that I, SAMUEL S. MATrHns, a citizen of the United States,residing at hilansfield, in the county of Richland and State of Ohio,have invented certain new and useful Improvements in Trolley-TireClamps, of which the following isa specifi-- cation. v

f My invention relates to a clamping device for engagingand supporting atrolley wire orv other conductor from an overhead support.

vvThe invention hasfor its object a con-- struction which willsimultaneously grip a conductor and the supporting hanger and the gripupon each will increase proportionatelyand such gripping effect isbrought about by a single operation and at the same time the device isrotatably adjustable with reference to the overhead supporting member.so that it may -be-brought into proper alinement with the trolley wireor other conductor. i i

These objects and others .which will be obviousto one skilled in the artare brought' about by the construction, relation and combination offelements fully described and set forth herein and Shown lin the drawingaccompanying this specification.

In the drawing:

In the preferred form of clamp embodying myinvention7 althoughlthere aremany modications which can be'made from this form andustill be withinthe scope ofmy' invention, I employ, a pair of clamping Y jaws l lprovided at their lower end with proper means 2 for engaglnga trolleywire conductor. At vthe upper end of each jaw 'is af ange 3; and arecess 4, the' flange vand recess on each Ajaw being semi-circular butwhen the two jaws larefplaced side'by side they approximate an entirecircular flange land recess. yN ear the upper end ofthe jaw members isavshoulder 5 which `I have sh'ownas having a beveledsurface although thissurface might be at other, angles than that shown in the drawing'. Oneymodifica.A tion of the shoulder. 5 isshown in Fig. 9'.

To 'support the device *embodying my invention from an overhead hangerH, Iuse a vsupporting member. 6 which is internally threaded :toi engagethe stud of theoverhead hanger and at its Ylower end is `provided with aflange extending inwardly indicated by 7 and forming a recess 8. v Theflange' 7 is adapted to yengage in the recess 4c vofthe V -aws and thelianee 3 isada-)tedto enga-Ge' h C in the recess. 8 of the supportingmember.

The flange -7 is not. entire but has an opening, from the outside asindicatedfbytlie numeral. 15in' F 8. V--This openingl permits theAassembling. of the aws and sup'- porting member as will bereadilygunderstood by considering the dottedlines shown in Fig. 8 torepresent the flange and recess 3 and respectively ofthe jaw member andpositioned yas shown with respect to :the supporting member 6. VThe jawrepresented byfthe dotted ,line is to be movedtoward thesupportingmember 6 and toregister with the openingl and it will be seenthat the aw will slip into the slot-l5 and fia-nge 3 will yenga-ge inlthe groove 8 and thenv by giving the jaw a'halt' turnfwithin lthesupicel portingmember 6 the second jaw- Can be operated thesame as thefirst and assembled with the :supporting member 6. This per'- supportmember to maintain the jaws in-a clamping position, and means to securethe device to a hanger.

5. A supporting device to engage and clamp a conductor comprising asupporting member, means to engage a hanger, clamping means rotatablymounted within the supporting member and held in clamping positionthereby and arranged to clamp a conductor, and an operating` membermounted on the supporting member and movable longitudinally thereof toengage the clamping means and move them into clamping engagement withthe conductor and means on the supporting member engaging means on theoperating member to prevent the removal of the parts ot' t-he device andlimit the longitudinal movement of the operating member in one directiononly.

6. A suspending device to engage and clamp a wire comprising asupporting member provided with means for engaging a hanger or supportand provided with internal means to engage a wire clamping means, wireclamping means provided with means for engaging and clamping a wire andalso having means to interlock with the internal means on thesupporting` member to prevent separation of the supporting` member andthe clamping means but permitting relative rotation, and a memberadapted to engage and move the clamping means into clamping engagementwith the wire and moving relatively to the supporting member.

7. A suspension device tol engage and clamp a conductor comprising asuspension member, a pair ot jaws and a collar mem-- ber, the suspensionmember adapted to support and retain the jaws together and provided withan internal recess andy shoulder and the jaws provided with an externalrecess and flange adapted to engage the internal flange and recessrespectively ot the sus-- pension member to permit ot free relativerotation, the collar adapted to move relatively to the jaws andsuspension member Vwhereby the jaws are made to grip the wire,

the suspension member also having means for attachment to a hanger orsupport.

8. A suspension device to engage and clamp a conductor comprising a pairot clamping jaws, Aa supporting member provided with an external recessand an opening to the recess to permit assembling the clamping jaws andthe supporting member, means on the jaws to engage the recess anuinterlock the parts together but to permit relative rotation, means onthe support member to engage a hanger or support, a

collar arranged to rotate with the'support member and to'be interposedbetween the jaws and the hanger and movable longitudinally to thesupporting member to move Athe jaws into engagement with the conductorwhen the collar enga-ges the hanger and is rotated.

9. A suspension device to engage and clamp a conductor con'xprising asupport-l ing member provided with means to secure the device to ahanger, two jaws, the jaws and supporting member provided with coactingmeans whereby the jaws are fulcrumcd within the suspension member andmounted to rotate relatively to each other, means projecting from eachjaw to be engaged to move the jawsinto clamping engagement with avconductor and means to' clamping engagement with the conductor.y 1l. Asuspending device to engage and.

clampa conductor comprising a` supporting member, means to engage ahanger, clamp- Y v ing means supported from within the supporting memberand held in clamping position thereby and arranged to clamp a conductor,an operating member mounted on the supporting member vand movablelongitudinally thereof to engage the clamping means and move them intovclamping en gagement with the conductor.

l2. A supporting-device to engage and clamp a conductor comprising asupporting member, means to engage a hanger, clamping means supportedfrom within the supporting member and arranged to clamp a conductor, anoperating member mounted on the supportingv member and movable longitudinally thereof to engage the clamping means and move them intoclamping en-` gagement with the conductor and means interposed. betweenthe operating and sup.v

porting members to limit the relative movement of these two members inone longitudinal direction. y

In testimony whereof I attix my signature.
